Phone wont turn on at all.

I was trying to switch from android 2.1 update 1 to 2.0.1 to root my motorola droid. I was in the bootloader installing spf recovery with RSD lite 4.6 when it said the installation failed. Now my phone wont turn on at all. I've tried holding x and the power button, plugging it in and holding up on the d pad, pulled battery and tried without the micro sd chip. I can't get anything to come up on the screen but light still comes out of the usb port when I plug the charger in. Help???
